The Cisco N7K-C7018 Nexus 7000 Series Switch Chassis is a flagship modular networking platform engineered for large-scale data center core, spine, aggregation, and service provider backbone deployments. Designed to deliver exceptional scalability, performance, and resiliency, this 18-slot chassis provides the foundation for mission-critical network infrastructures in enterprise, cloud, and hyperscale environments.
Featuring an advanced 18-slot architecture with 16 I/O module slots and 2 dedicated supervisor slots, the N7K-C7018 supports a broad range of high-density line cards and fabric modules, enabling organizations to scale network capacity as business demands grow. The chassis delivers multi-terabit switching performance exceeding 15 Tbps, making it ideal for handling massive east-west and north-south data center traffic flows.
Built on Cisco's distributed fabric architecture, the N7K-C7018 provides ultra-low latency, wire-speed forwarding, and non-blocking performance for high-bandwidth applications. The platform supports up to 768 10 Gigabit Ethernet ports, 96 40 Gigabit Ethernet ports, or 32 100 Gigabit Ethernet ports, offering unmatched flexibility for modern data center and cloud networking requirements.
Running on Cisco NX-OS, the chassis supports advanced technologies including VXLAN, Virtual Device Contexts (VDCs), MPLS, FCoE, virtualization services, advanced QoS, and network segmentation. These capabilities help organizations build scalable, secure, and highly automated network infrastructures.
The N7K-C7018 is engineered for maximum availability with redundant supervisor modules, fabric modules, power supplies, and hot-swappable fan trays. Support for in-service software upgrades (ISSU), Stateful Process Restart (SPR), and comprehensive redundancy ensures continuous operation and minimizes downtime in mission-critical environments.
Ideal for data center spine architectures, enterprise core switching, cloud computing platforms, hyperscale environments, and service provider backbone networks, the Cisco N7K-C7018 Nexus 7000 Series Chassis delivers industry-leading scalability, high availability, and performance for next-generation networking infrastructures.
